  • An expedient embodiment, especially of the insulation can provide that this insulation or the insulating container is spaced from the inside of the pressure vessel or the inside of the pressure vessel only partially touched. As a result, an insulating space can still be kept free between the pressure vessel and the insulation, which improves the insulating effect.
  • At least the digestion container may consist of a temperature and / or chemical resistant material, for example of metal, ceramic and / or plastic. Even plastic is possible because the digestion tank itself can not absorb pressure, but transmits it via the water jacket to the outer pressure vessel.

  • the thermal development influencing the calorimetric process is avoided by sliding friction of such a shaft, which requires a seal which is effective against high pressure.
  • more than one temperature sensor may be provided in the intermediate space which is arranged between the decomposition container and the pressure vessel and which receives water or an incompressible liquid during use, wherein these several temperature sensors may preferably be evenly distributed. As a result, the measuring speed and the measuring accuracy can be increased.
  • one or more temperature sensors can be arranged on the outside of the pressure vessel. Thus, it can be checked whether and how much heat has possibly leaked through the pressure vessel or what temperature difference exists between the two sides of the wall of the pressure vessel.

  • the shape of the combustion chamber within the digestion container can be arbitrary and arched over at least a portion or be cylindrical over the entire height or designed as a bellows to allow a space-saving form, but not to pay attention to compressive strength, because the pressure is advantageously transmitted through the liquid jacket on the outer container serving as a pressure vessel.
  • the entire calorimeter can save space, so with a clear lower total volume than previous conventional calorimeters are produced. Its transport is correspondingly easy and simple, and correspondingly fast calorimetric measurements can be carried out at different points or places. In this case, because of the incompressibility of the liquid, even a low compressive yield or possibly a low extensibility of the digestion container may be sufficient.
